CARTRIDGE EXTRACTOR FOR FIREARMS.

Application filed. August 23, 1921. Serial No. 494,548.

To all whom 2'25 may concern:

Be it known that I, RUDoLF VON FROM- MER, a citizen of Hungary, residing at Budapest, IX Soroksari ut 158, have invented certain new and useful Improvements in Cartridge Extractors for Firearms, of which the following is a specification.

The subject of my present invention is a cartridge extractor consisting of two parts. One part is an inelastic hook which works in the manner of a two armed lever and serves to extract the cartridges; the other part is a flat spring, which is provided to operate the extracting hook and at the same time to keep it in position in its groove.

The hook-shaped portion of the extractor is formed and embedded in the breech block in such a Way, that it is allowed to make, against the tendency of the spring, a swinging motion required for its operation, without a bore and a pin, or the like, being needed.

Thus, the cartridge extractor according to my invention, is extraordinarily simple in its construction, it is reliable in operation and indestructible. It is also easily inserted or removed and can be made of such small size that it can be adapted even to the smallest size of firearms. It is so con structed that the separate spring is subjected only to a small predetermined tension as compared with the usual cartridge extractors consisting of one piece only, where the spring generally is subjected to a bending tension.

My invention is shown by way of illustration on the annexed drawing, in which Fig. 1 is a longitudinal section of the breech block fitted with my new cartridge extractor,

Fig. 2 a cross section of the breech block on the line} AB of Fig. 1 without the extractor, while Figs. 3 and 4 are top plan views of the extracting hook and the flat spring.

The hook 1, which grips the edge of the cartridge shell, is embedded in a corresponding groove of the breech block 2 in such a way, that the nose 3, provided at the lower part of the hook, enters a notch 4 in the breech block. The nose 3, the notch 4 and the protruding part 17 above the notch, are so arranged, that the hook 1 can swing out from its resting position shown by Fig. 1 to a certain degree about the protruding part 7 At this swinging motion, the shoulder 5 of the hook 1 turns toward the middle axis of the breech block. In the groove of the breech block 2 into which the cartridge extractor is fitted, there is arranged a flat spring 6, whose resilient end is placed underneath the shoulder 5 of hook 1, while the other end of this spring is embedded in a recess 8 of the breech block. The spring 6 presses constantly the shoulder 5 of hook 1 outward, so that the head of hook 1 is moved toward the axis of the breech block. This motion is limited by the bottom of the groove on the breech block 2, upon which the hook 1 is lying. The ejection of the hook by the spring 6 is prevented by the nose 3, which extends into the notch 4. On the lower surface of the shoulder 5 there is provided a recess 9, against which bears the end of spring 6 so as to prevent anylongitudinal movement of the hook. It is thus evident, that the hook 1 forms a two armed lever, adapted to pivot about the protruding part 7.

In order to insert the cartridge extractor one first places one end of the spring 6 into the recess 8, and after putting the hook upon the spring, one presses it into its right position. Thereby the spring 6 is snapped under the shoulder 5 and the hook is thus fixed in position. In removing the extractor the forward end of the spring 6 is simply pressed down which releases the hook which then can be removed.

I claim as my invention:

1. A cartridge extractor for fire-arms comprising in combination with the breechblock, an inelastic hook-shaped member adapted to engage in a notch in the breechblock so as to be pivotally held thereby and forming a two-armed lever, and a separate fiat spring engaging the rear end of the said hook-shaped member so as to hold the same in its operative position.

2. A cartridge extractor as specified in claim 1, in which the said hook-shaped member is provided with a recess, the said fiat spring engaging in said recess so as to act against the said hook-shaped member to force its book into operative position. at the same time preventing longitudinal movement of said member.

In testimony whereof I affix my signature in presence of two witnesses.
